Simulation the axial-flow fans and its performance evaluation.

This thesis studies to simulate the axial flow fans by using the CFD software. Designing two geometries types of axial flow fans which had different twist angles and the same contour¡]70¡Ñ70¡Ñ15 mm¡^with the Joukowski airfoil; then, defining the boundaries shapes identical with the experimental instrument.
In the part of numerical calculation, varying the rotation speed ¡]rpm¡^,volume flow rate¡]CFM¡^and seven types of turbulence models to simulate the flow fields and evaluate the axial flow fans performance curves. Utilizing the comparison of the experimental and simulate results to provide the appropriate turbulent models to periodic the performance curve precisely.
